Overall looks good. Two non-critical comments:

1. I guess I'm not fully up-to-speed on what the api-napa instance is, but I'm a little confused about the code that sort of uses that term interchangeably with "dev instance". To me "dev" is what's deployed on api-dev.microbiomedata.org. It might make more sense to me to remove the get_runtime_client method and the --use_dev_api flag, and let it all be driven by environment variables. Want to use the api-napa instance? Okay, then set your API_HOST envar accordingly. That's just my outsider view of how I'd expect something like this to work. If that doesn't make sense to you, forget I said anything.
2. It doesn't look like python-dotenv is listed in main.in but we get it as a transitive dependency of other stuff. If we're using it directly we should list it as a direct dependency.
